What Causes the Odor in Oshan Air Conditioning?
2 Answers
The reason for the odor in Oshan air conditioning is: dust accumulation on the air conditioning filter and copper sheets inside the air conditioner. Once the heat exchanger fins inside the air conditioner are completely covered with dust, it may lead to blockage, resulting in an unusual odor. When the air conditioner is turned on, this odor will spread. Oshan is a passenger car brand under Changan, with models including: Changan Oshan Kosei, Changan Oshan Koshang, Changan Oshan X70A, Changan Oshan CX70T, Changan Oshan A800, and others. Taking the Changan Oshan Kosei as an example, it is a mid-size SUV with dimensions of 4830mm in length, 1868mm in width, and 1750mm in height, and a wheelbase of 2800mm. It features a MacPherson strut front suspension and a multi-link independent rear suspension.
The foul smell in Oshan air conditioning is often caused by mold growth on the evaporator. After each parking, the condensed water doesn't dry completely, especially in humid environments, allowing bacteria to multiply rapidly and produce that musty odor. I've personally repaired many units and found that dirty filters or foreign objects in the air conditioning ducts can also cause this issue. Don't underestimate it - the pungent smell may affect health and cause fatigue while driving. I recommend trying a new filter first, which is inexpensive and effective. If that doesn't work, clean the evaporator with specialized cleaning spray to eliminate bacteria and odors. Before parking, turn off the AC and let the fan run longer to dry the interior, preventing recurrence. In short, don't delay - address it early to ensure fresh air.
